CORRECT.
◍ quantum numbers (name, visual meaning, symbol). Answer:
Principle : Shell -- energy level / size (n)
Angular Momentum : Subshell -- cloud shape (l)
Magnetic : Orbital -- cloud shape variant (m_{l})
Spin : Spin -- electron spin (up/down) (m_{s})
◍ subshell letters (in order and shape name). Answer: s (sphere), p
(dumbbell), d (pedal), f (double pedal)
◍ how to setup orbital order. Answer: orbitals in the same column,
energy levels in the same row.
shave off the top corner.
◍ Group 1, Group 2, Group 7, Group 8 electron config values.
Answer: s^1, s^2, p^5, p^6
,◍ monovalent, divalent. Answer: monovalent: 1 electron needed to
gain or lose to fill valence
divalent: 2 electrons needed to gain or lose to fill valence
◍ equilibrium spacing. Answer: distance between two atoms where
net force is zero.
minimum energy level.
◍ bonding energy. Answer: the amount of energy needed to separate
two charged particles at an infinite distance.
◍ ionic bonding properties and reason. Answer: melting point : strong
bonds
brittle : rigid/fixed atom arrangement
electrically insulated : very stable electrons
◍ metallic bonding and ion core. Answer: ion cores is the nucleus and
non-valence electrons of an atom.
metals are made of this. the valence electrons are shared amongst
themselves.
, ◍ van der Waals forces. Answer: very weak intermolecular forces of
attraction
◍ IMFs in inert gasses. Answer: only van der waals
◍ anions for hydrogen bonding. Answer: fluorine, oxygen, chlorine
◍ metal-ionic bonds. Answer: bonds of a substance with considerable
ionic and metallic bonds.
occurs when two metals with large electronegativities are together.
as electronegativity difference increases, so does percent ionic bond.
◍ major unit cells. Answer: FCC, BCC, HCP, Simple
◍ FCC measurements & characteristics. Answer: Reference
Measurement: 4r is face diagonal
Edge Length : 2 sqrt(2) x r
Volume : 16 sqrt(2) x r^3
Atoms : 4
Coordination : 12
APF : 0.74
